Seismic Imaging

Oil Companies have to spend a lot of money on digging oil. They don't like to waste their time and money on an unproductive spot. There are so many failures in spotting the oil surface.
Seismic Imaging is one of the most important innovations in Oil Exploration helps in reducing the number of unproductive wells and useful to find productive wells.
                            
In the seismic imaging process, an energy source such as a vibrator truck sends sound waves deep into the earth. This relies on the idea that sound bounces off and travels in different ways. Special devices called geophones are positioned on the surface, which receives the sounds that bounce back up and send the information to recorder trucks.
Engineers and geophysicists study the recorded sound waves to interpret what kinds of layers of rock formation lie in that location. This way, they can construct 3-D images of what lies under the surface.
